What problems do scientists urgently need to solve today?
In fact, it can be summarized as: health, energy and environment. Health is a concern of all mankind. The continuous progress of medicine is to benefit human health, and cancer is a great threat to human health. There are about180,000 new cancer cases in the world every year, so cancer is also listed as the number one killer threatening human health. Although there are relatively perfect cancer treatment methods, the cure rate is very low for patients with advanced cancer, so cancer is one of the hot issues that scientists urgently need to solve.
Now targeted therapy can effectively curb the development of the disease and eliminate cancer cells. In the future, with the continuous development of the research field of cell molecular biology, there will definitely be more methods to treat cancer.
The energy problem is also the most concerned issue of mankind today. The development of civilization is inseparable from energy. At present, the energy structure of human beings is relatively simple, mainly relying on fossil fuels, and hydropower, wind power, solar energy and nuclear power only account for a small proportion, so huge energy consumption will definitely bring environmental pollution.
Is there any way to solve the problem of single energy structure of human beings?
The solution is always more difficult than it is. At present, controlled nuclear fusion is the most promising country. Now all the major countries in the world are vying for the top spot in this field, and China is also the vanguard in this field. Previously, China's "Oriental Hyperloop" EAST achieved good results in the high confinement mode plasma operation of 10 1.2 seconds, and the electron temperature in the plasma center was achieved at the end of 20 18.

Controlled nuclear fusion is favored by scientists because of its high energy density, controllability, no pollution (or less pollution) and abundant available resources. Three isotopes of hydrogen, deuterium and tritium, can be used for nuclear fusion, but different formulations require different conditions. At present, the most promising fusion method is deuterium-tritium fusion with the lowest requirements. In this way, the tritium nuclei stored on the earth can be used by human beings for tens of thousands of years, while deuterium can be directly extracted from seawater, which is extremely abundant, though not inexhaustible.
Only with it can human civilization reach a new level.
If this pollution-free energy can be obtained, the environmental problem will be solved naturally.
Health and environment are related to the quality of human life, and energy is related to the progress of human civilization. If these two wings can be stronger, then humans can fly farther.
